摘要
RNA干扰(RNA interference,RNAi)是一种由双链RNA诱发的转录后水平的基因沉默现象,是近几年发展起来的基因表达调节新机制,广泛地存在于真菌、植物和动物中。到目前为止,已有很多试验证明,RNAi作为一种基因功能研究的新手段,在动物繁殖研究中发挥了极其高效的作用。作者主要介绍了RNAi的研究历史、分子机制、作用特点、生物学意义及在动物繁殖中的应用。
RNA interference(RNAi) is a phenomenon of post-transcript gene silencing induced by double strand RNA and a new mechanism of regulating gene expressing,which widely exists in epiphyte,plants and animals.So far,a number of tests have proved that RNAi as a new method to study gene function has played a very effective role in studying of animal breeding.This study aimed to introduce the discovery of RNA interference,molecular mechanism,role of the characteristics,the significance of biology and wide application of RNAi in animal breeding.
